Access control installation in Massachusetts: who may do it

The law spells it out in Massachusetts, though it’s rare elsewhere. Under Chapter 141, section 1, a security system is a wired, inherently power limited setup built for access control, surveillance and intrusion detection. A circuit is inherently power limited when its design means it doesn’t need overcurrent protection.

Fire warning wiring and security wiring are combined under "systems" in that same chapter. So a systems license lets you wire card readers and fire alarms. Under their own scope rules, journeyman and master electricians may do security system work as well.

Two systems licenses come from the Board of State Examiners of Electricians. Someone who runs cable and installs readers gets a Systems Technician license. A company that has those technicians on staff operates from a regular place of business and carries a Systems Contractor license.

Section 1A says no one may do this work without a license from the electricians board. Chapter 147 says the firm doing security systems must also get licensed through the Division of Occupational Licensure.

• To take the Technician exam, you need 300 hours of board‑approved training, plus 4,000 hours of work spread over 2 years or more.
• Contractor exam requirements: you hold a Massachusetts technician license, you’ve worked at least 1 year and you’ve finished 75 hours of education.
• The technician path costs you $31 for the application and another $104 for the license; the contractor path runs $66 and $155. Altogether, the exam fee is $135.

The board has issued guidance on wireless systems. When every part talks wirelessly and nothing is hard‑wired, the system doesn’t count as a security system. Its power has to come from a battery or from a plug into an outlet that already exists.

The exemption is quite limited. A maglock that draws power from a supply, or a reader wired back to a controller, counts as hard‑wired. The board notes the guidance isn’t for every technology, so check with them before you rely on it.

Go to the state’s license check and enter a license number, or a name along with the license type. Search for an active record under systems technician, systems contractor or electrician.

From April 24, 2026 the Massachusetts Electrical Code governs door wiring; it now draws on the 2026 NFPA 70. Rules for egress through locked doors are in the tenth edition building code, which rests on the 2021 IBC. That code became the sole building code that applies after June 30, 2025.

A reciprocity agreement is in place between Massachusetts and New Hampshire. New Hampshire installers still submit their application for a Massachusetts license via the state portal before the job begins.
